    • A method for manufacturing shoe components using EVA copolymer of film shape having a thickness of 0.01 to 2 mm, preferably 0.1 to 1.0 mm and a surface roughness variations which cannot be easily discriminated through touch or sight, and a shoe component manufactured by the method are provided. The method overcomes the drawbacks caused during the process of manufacturing a shoe component with different mechanical physical properties or colors. The method allows for ease of manufacture of a shoe component with two or more types of colors or physical properties, through a single foam molding process using a film with less variation and ease of processing, to thereby simplify manufacturing procedures and reduce manufacturing costs. In addition, a high quality shoe component with no additional seam-line is obtained.
    • 使用厚度为0.01〜2mm,优选为0.1〜1.0mm的膜状的EVA共聚物和通过触摸或视觉不能容易地判别的表面粗糙度变化以及通过该方法制造的鞋部件来制造鞋部件的方法是: 提供。 该方法克服了在制造具有不同机械物理性质或颜色的鞋部件的过程中引起的缺点。 该方法允许通过使用具有较小变化和易于加工的膜的单一泡沫模制方法容易地制造具有两种或更多种颜色或物理性质的鞋部件,从而简化制造程序并降低制造成本。 另外,获得了没有附加缝线的高质量的鞋部件。
